Description

Technical Field

[0001] This utility model relates to the field of oil processing technology, and in particular to a highly efficient rapeseed oil refining device for removing impurities. Background Technology

[0002] Rapeseed oil has a long history of extraction. Initially, people used a simple pressing method to obtain rapeseed oil. The ancient pressing tools were mainly wooden wedge-shaped oil presses. Pressure was applied by human or animal power to squeeze the oil out of the rapeseed. This method was relatively primitive, but it laid the foundation for oil extraction. In the traditional processing of rapeseed oil, the crude oil contains a variety of impurities, including mechanical impurities, phospholipids, free fatty acids, pigments, gums, and trace amounts of metal ions.

[0003] However, the above-mentioned device relies on the squeezing between the baffle and the push plate to remove oil. However, the resistance provided by the baffle by the spring is limited, and the extraction of small amounts of rapeseed oil from natural wax is still limited.

[0004] The existing patent (publication number: CN220714965U) discloses a rapeseed oil refining equipment. By starting a rotating motor, a threaded rod is rotated. The rotation of the threaded rod, in conjunction with the limiting rod and the inner wall of the limiting port, allows the two pressure plates to approach each other, thus squeezing the material fed through the feed inlet. This can fully squeeze out a small amount of rapeseed oil. After the two pressure plates separate, the crushed blocks can be ejected under the force of the crushing spring and perform a crushing operation on the cake-shaped material, which can disperse the material. When the material is squeezed again, the rapeseed oil can be fully squeezed out.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing high-efficiency rapeseed oil refining devices are not convenient for multiple filtrations of the refined rapeseed oil, nor are they convenient for collecting the filtered residues, resulting in resource waste. Furthermore, they are not convenient for reducing the free fatty acid content in the rapeseed oil, thus affecting the quality of the subsequent rapeseed oil.

[0006] Therefore, a highly efficient rapeseed oil refining device for removing impurities is proposed. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 The present invention provides the following technical solution:

[0031] A highly efficient rapeseed oil refining device for removing impurities includes a support platform 1, a filter assembly 5 disposed on the left side of the top of the support platform 1, and a reaction assembly 6 disposed on the top of the support platform 1.

[0032] The filter assembly 5 includes a filter box 501 bolted to the top of the support platform 1. A support frame 502 is bolted inside the filter box 501. Three filter plates 503 are bolted to the right side of the support frame 502 and are stacked. A stop block 504 is slidably connected inside the support frame 502. A limit block 505 is fixedly connected to the left side of the stop block 504. A limit rod 506 is bolted to the top of the limit block 505. A rack plate 507 is fixedly connected to the top of the limit rod 506. A gear rod 508 is meshed with the inner side of the rack plate 507. A support rod 509 is fixedly connected to the top of the gear rod 508. The support rod 509 passes through the filter box 501. An adjusting rod 510 is fixedly connected to the top of the support rod 509.

[0033] In this embodiment: the added rapeseed oil raw material is initially filtered by three filter plates 503. The upper filter plate 503 has a larger pore size, which can remove larger particulate impurities first. The pore size of the lower filter plate 503 gradually decreases, further intercepting smaller particulate impurities, thereby achieving preliminary classification filtration of impurities of different particle sizes in the rapeseed oil. During the filtration process, the impurities are intercepted by the filter plates 503, forming residue. When it is necessary to clean the residue, the adjusting rod 510 is rotated. The rotation of the adjusting rod 510 then drives the support rod 509 to rotate. 509 passes through the filter box 501 and its top is fixedly connected to the adjusting rod 510. The rotation of the support rod 509 drives the gear rod 508 to rotate. Since the gear rod 508 is meshed with the inner side of the rack plate 507, the rotation of the gear rod 508 will cause the rack plate 507 to move. The movement of the rack plate 507 is transmitted to the limiting block 505 through the limiting rod 506. The limiting block 505 is fixedly connected to the left side of the stop block 504, so the stop block 504 will slide inside the support frame 502. Then, by adjusting the position of the stop block 504, the falling of the residue can be controlled.

[0034] Specifically, such as Figure 3 As shown, the reaction assembly 6 includes a reaction vessel 601 bolted to the top of the support platform 1. The inner wall of the reaction vessel 601 has a cavity 602. A heating wire 603 is installed inside the cavity 602. Feed ports 604 are provided on both sides of the top of the reaction vessel 601. A top cover 605 is snapped into the inside of the feed port 604.

[0035] Specifically, such as Figure 3 As shown, a drive motor 606 is bolted to the top of the reactor 601, and a connecting rod 607 is fixedly connected to the output end of the drive motor 606. A rotating rod 608 is fixedly connected to the outside of the connecting rod 607.

[0036] Specifically, such as Figure 3 As shown, a conveying pipe 609 is connected to the left side of the reactor 601, and a conveying pump 610 is connected to the outside of the conveying pipe 609. The water inlet of the conveying pump 610 is connected to the bottom of the filter box 501.

[0037] In this embodiment: the filtered rapeseed oil is transported to the reaction vessel 601 via the delivery pump 610 and the delivery pipe 609. The left side of the reaction vessel 601 is connected to the delivery pipe 609 to receive oil from the filter box 501. At the same time, the heating wire 603 installed in the cavity 602 can heat the rapeseed oil in the reaction vessel 601 to meet the temperature conditions required for different refining reactions. Then, the alkali solution is added through the feed port 604 to reduce the content of free fatty acids. Then, the top cover 605 is snapped into the feed port 604 to prevent impurities from entering and materials from splashing out. Then, after the drive motor 606 is started, the connecting rod 607 at its output end drives the outer rotating rod 608 to rotate, stirring the oil in the reaction vessel 601 and promoting the chemical reaction. The rapeseed oil undergoes the corresponding chemical reaction in the reaction vessel 601 to remove impurities and reduce the content of free fatty acids in the rapeseed oil.

[0038] Specifically, such as Figure 4 As shown, a transfer pump 7 is bolted to the bottom of the support platform 1. The water inlet of the transfer pump 7 is connected to a connecting pipe 8, which is connected to the reactor 601. The output end of the transfer pump 7 is connected to a transfer pipe 9. A negative pressure tank 10 is bolted to the right side of the top of the support platform 1. A filter screen plate 11 is bolted inside the negative pressure tank 10. A vacuum pump 12 is installed on the top of the negative pressure tank 10.

[0039] Specifically, such as Figure 6 As shown, a storage tank 13 is bolted to the right side of the top of the support platform 1. A liquid level sensor 14 is installed on the top of the storage tank 13. A collection pipe 20 is connected to the left side of the storage tank 13 and is connected to the negative pressure tank 10.

[0040] In this embodiment: By setting up a transfer pump 7, connecting pipe 8, transfer pipe 9, negative pressure tank 10, filter screen 11, and vacuum pump 12, the refined rapeseed oil in the reactor 601 is pumped into the transfer pump 7 via the connecting pipe 8, and then transported to the negative pressure tank 10 via the transfer pipe 9. The vacuum pump 12 set at the top of the negative pressure tank 10 works to create a negative pressure environment inside the negative pressure tank 10. The filter screen 11 bolted inside the negative pressure tank 10 further filters the incoming rapeseed oil. Under the action of negative pressure, the oil can pass through the filter screen 11 more quickly, which also helps to remove some volatile impurities and residual fine particles, achieving multiple filtration and improving the purity of the rapeseed oil. By setting up a storage tank 13, liquid level sensor 14, and collection pipe 20, the refined rapeseed oil filtered by the negative pressure tank 10 enters the storage tank 13 for storage through the collection pipe 20. The liquid level sensor 14 monitors the liquid level in the tank in real time, so that the operator can understand the storage status in time and facilitate the control of the production process.

[0041] Specifically, such as Figure 5As shown, a water storage tank 2 is bolted to the top of the filter box 501, and a water pump 3 is installed on the right side of the water storage tank 2. The output end of the water pump 3 is connected to a water pipe 4, which is connected to the filter box 501.

[0042] Specifically, such as Figure 5 As shown, the bottom of the filter box 501 is connected to a slag discharge pipe 15, and a control valve 16 is provided on the outside of the slag discharge pipe 15.

[0043] In this embodiment: by setting up a water storage tank 2, a water pump 3, and a water pipe 4, when there is residue remaining on the filter plate 503, the water pump 3 on the right side of the water storage tank 2 is started. Then, the water pump 3 transports the water in the water storage tank 2 to the filter box 501 through the water pipe 4. After the water washes the filter plate 503 in the filter box 501, it can carry some impurities and move to the top of the slag discharge pipe 15 through the position blocked by the baffle, so as to collect the residue and clean the filter plate 503 at the same time to prevent the residue from clogging and affecting its filtration effect. By setting up the slag discharge pipe 15 and the control valve 16, by opening the control valve 16, the cleaned residue can be discharged through the slag discharge pipe 15 to collect the residue, avoid waste of resources, and flexibly handle the residue without affecting the filtration process.

[0044] Specifically, such as Figure 1 As shown, a protective sleeve 17 is fitted on the outside of the reactor 601, and the protective sleeve 17 is made of rubber.

[0045] Specifically, such as Figure 1 As shown, the top of the filter box 501 is connected to a feed pipe 18, and the top of the feed pipe 18 is bolted with a flange 19.

[0046] In this embodiment: by setting a protective sleeve 17, when the reactor 601 is accidentally bumped, the rubber protective sleeve 17 can play a buffering role when the reactor 601 is bumped, reducing the impact force on the reactor 601 tank. By setting a feed pipe 18 and a flange 19, the flange 19 connects the feed pipe 18 to the external pipeline for conveying rapeseed oil raw materials, so that the rapeseed oil raw materials can enter the filter box 501 through the feed pipe 18, so as to facilitate the connection with the external pipeline, and at the same time ensure that the rapeseed oil raw materials can smoothly enter the filter box 501 for preliminary filtration.

[0047] Working Principle: In the process of using the high-efficiency rapeseed oil refining device, rapeseed oil raw material is first added through the feed pipe 18 and flange 19, allowing it to enter the filter box 501. The raw oil then undergoes preliminary filtration through three filter plates 503. The upper filter plate 503 has a larger pore size, removing larger particles of impurities first. The lower filter plate 503 has a gradually decreasing pore size, further intercepting smaller particles of impurities. This achieves preliminary grading filtration of impurities of different particle sizes in the rapeseed oil. During the filtration process, impurities are intercepted by the filter plates 503, forming residue. When it is necessary to clean the residue, the adjusting rod 510 is rotated. The rotation of the adjusting rod 510 then drives the support rod 509 to rotate. Because the support rod 509 penetrates the filter box 501 and its top... The part is fixedly connected to the adjusting rod 510. The rotation of its support rod 509 drives the gear rod 508 to rotate. Since the gear rod 508 is meshed with the inner side of the rack plate 507, the rotation of the gear rod 508 will cause the rack plate 507 to move. The movement of the rack plate 507 is transmitted to the limiting block 505 through the limiting rod 506. The limiting block 505 is fixedly connected to the left side of the stop block 504, so the stop block 504 will slide inside the support frame 502. Then, adjusting the position of the stop block 504 can control the falling of residue. When there is residue left on the filter plate 503, the water pump 3 on the right side of the water storage tank 2 is started. Then, the water pump 3 transports the water in the water storage tank 2 to the filter box 501 through the water pipe 4. After the water washes the filter plate 503 in the filter box 501, it can carry Some impurities move to the top of the slag discharge pipe 15 after being blocked by the baffle. Then, the control valve 16 on the outside of the slag discharge pipe 15 is opened to allow the residue to be discharged through the slag discharge pipe 15, so as to facilitate the collection of residue, avoid resource waste, and flexibly handle residue without affecting the filtration process. Then, the filtered rapeseed oil is transported to the reaction vessel 601 through the conveying pipe 609 via the conveying pump 610. The left side of the reaction vessel 601 is connected to the conveying pipe 609 to receive oil from the filter box 501. At the same time, the heating wire 603 installed in the cavity 602 can heat the rapeseed oil in the reaction vessel 601 to meet the temperature conditions required for different refining reactions. Then, the alkali solution is added through the feed port 604. The alkali solution is used to reduce the content of free fatty acids. The top cover 605 is snapped into the feed port 604 to prevent impurities from entering and materials from splashing out. Then, the drive motor 606 is started, and its output connecting rod 607 drives the outer rotating rod 608 to rotate, stirring the oil in the reaction vessel 601 and promoting the chemical reaction. This allows the rapeseed oil to undergo the corresponding chemical reaction in the reaction vessel 601 to remove impurities and reduce the free fatty acid content. After the reaction is complete, the rapeseed oil is transported through the connecting pipe 8 and, under the action of the transfer pump 7, through the transfer pipe 9 to the negative pressure tank 10. The vacuum pump 12 installed at the top of the negative pressure tank 10 operates, creating a negative pressure environment inside the tank. The filter screen 11 bolted inside the negative pressure tank 10 further filters the incoming rapeseed oil under the action of negative pressure.The oil passes through the filter screen 11 more quickly, which helps remove some volatile impurities and residual fine particles, achieving multiple filtration and improving the purity of the rapeseed oil. The refined rapeseed oil, after filtration in the negative pressure tank 10, enters the storage tank 13 for storage. The liquid level sensor 14 monitors the oil level in the tank in real time, allowing operators to understand the storage situation and ensuring the safety and stability of the production process.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
